Assay Office Punch/Laser Marking (INCM)


In accordance to European Union Law, all silver, gold and platinum products, must be hallmarked and the hallmark must include the type of precious metal and its purity.

All Patzi Creative Design jewellery, handmade in Portugal having incorporated precious metals such as silver or gold, are all duly certified by the INCM (Assay Office)

The INCM (Assay Office) verifies and guarantees in an independent fashion, the legal touches of goldsmithing, holding accountable both the author of the artefact as well as the one who controls its touch, ensuring in this way total exemption.

Should you have any doubts or concerns about the authenticity of the hallmark marks, we advise you to call on the services of the INCM so that this can be verified.
